The Hunley Revealed: 3D Documentation, Deconcretion, and Recent Developments in the Investigation of the H.L. Hunley Submarine.

Summary

Beginning in 2014, the conservation staff at Clemson University’s Warren Lasch Conservation Center (WLCC) in Charleston, South Carolina have been removing the marine concretion from the hull of the American Civil War submarine H. L. Hunley. In parallel with this, the archaeological team has been documenting the condition of the hull, as well as the concretion layers and hull features revealed by the deconcretion process. This documentation has involved photography, direct measurements, and 3D scanning. This paper will discuss the implemented strategy for recording the concretion, the techniques used to document and study the revealed hull and unique features, and their archaeological significance. Recent progress in the overall archaeological investigation of the H.L. Hunley submarine will also be addressed.
